研究了木屑与原生塑料和回收塑料（HDPE和PP）制备的木塑复合材料的吸水性能。木粉由锯末制备，并与不同的原生或回收塑料以50重量%的纤维负载混合。将混合的材料压缩模塑成板。在不同温度（25、50和70 ℃）下浸入蒸馏水中2和24小时后，测定制造的WPC的吸水率。含有再生塑料的WPC表现出更高的吸水率，特别是当两种再生塑料混合在一起时。浸泡温度对吸水率有显著影响。
Water absorption of wood plastic composites (WPCs) manufactured from sawdust and virgin and recycled plastics (HDPE and PP) was studied. Wood flour was prepared from sawdust and mixed with different virgin or recycled plastics at 50% by weight fiber loading. The mixed materials were compression molded into panels. Water absorption of manufactured WPCs was determined after 2 and 24 h immersion in distilled water at different temperatures (25, 50 and 70 C). WPCs containing recycled plastics exhibited higher water absorption especially when the two recycled plastics were mixed together. Immersion temperature had a significant effect on water absorption.
